Colomascirtus  new genus

Colomascirtus  . Type species: Hyla larinopygion Duellman, 1973  .

Definition. Large, colorful frogs attaining SVLs of more than 70 mm ( Fig. 12 AView FIGURE 12. A); cloacal region swollen; white parietal peritoneum and mental gland absent; stream-dwelling tadpoles with large oral discs directed ventrally and having one or two complete rows of marginal papillae; LTRF 4–14 / 6–17. Chromosome complement unknown.

Content. Seventeen species: Colomascirtus antioquia* (Rivera-Correa & Faivovich)  , armatus (Boulenger)  , caucanus* (Ardila-Robayo, Ruiz-Carranza, & Rua-Trujillo), charazani (Vellard)  , chlorosteus* (Reynolds & Foster), condor* (Almendáriz, Brito-M., Batallas-R. & Ron), criptico  (Coloma, Carvajal-Endara, Dueñas, Paredes- Recalde, Morales-Mite, Almeida-Reinoso, Tapia, Hutter, Toral-Contreras & Guayasamin), larinopygion (Duellman)  , lindae (Duellman & Altig)  , pacha (Duellman & Hillis)  , pantostictus (Duellman & Berger)  , princecharlesi (Coloma, Carvajal-Endara, Dueñas, Paredes-Recalde, Morales-Mite, Almeida-Reinoso, Tapia, Hutter, Toral-Contreras & Guayasamin)  , psarolaimus (Duellman & Hillis)  , ptychodactylus (Duellman & Hillis)  , staufferorum (Duellman & Coloma)  , tapichalaca (Kizirian, Coloma & Paredes-Recalde)  , and tigrinus  (Mueses- Cisneros, & Anganoy-Criollo), all new combinations.

Distribution. Cloud forest and subparamo in the Andes of Colombia and Ecuador, and in southern Peru and Bolivia.

Etymology. The generic name is a patronym for Luis A. Coloma in combination with the Greek scirtao verb meaning to leap. Coloma has been a principal researcher on, and conservationist of, frogs in the northern Andes. The gender is masculine.

Remarks. Members of Colomascirtus  were first defined as the Hyla larinopygion  Group by Duellman and Hillis (1990) and subsequently by Duellman et al. (1997) and Rivera-Correa & Faivovich (2013). Coloma et al. (2012) provided a thorough account of the morphology, osteology, development, calls, and ecology of the species in the genus. A detailed morphological study of the tadpoles by Sánchez (2010) revealed two structures (shelf on upper jaw sheath and crown-like ornamentation around naris) that help define two groups of species that are not concordant with the then recognized Hyla bogotensis  and Hyla larinopygion  groups ( Coloma et al 2012).

Two species, Colomascirtus armatus  and C. charazani  , have been placed in a group variously recognized as the Hyla armata  Group (Duellman et al. 1997) or the Hyloscirtus armatus  Group (De la Riva et al. 2000; Lötters et al. 2005). These two species occur in southern Peru and Bolivia, leaving a gap of more than 2000 km from southern Ecuador to southern Peru. Males of these large frogs have clusters of keratinized spines on the prepollex and on the proximal ventral surface of the humerus ( Fig. 12View FIGURE 12. A B). The LTRF in tadpoles is 13–14 / 16–17, notably greater than in other species of Colomascirtus  , 4–9 / 6–12 ( Sánchez 2010). In our tree ( Fig. 4View FIGURE 4) C. armatus  and C. charazani  are in a well-supported (100 %) clade that is sister of all other Colomascirtus  . This same arrangement was shown in molecular phylogenetic trees by Faivovich et al. (2005), Wiens et al (2010), Pyron & Wiens (2011), Coloma et al (2012), and Rivera-Correa & Faivovich (2013). In the phylogenetic analysis by Almendáriz at al (2014), a different topology was recovered with C. armatus  and C. charazani  as sister taxa of Hyloscirtus  ; however their arrangement had less support and was based on fewer genes than those by Coloma et al (2012) and Rivera- Correa & Faivovich (2013).
